Abstract

This article presents data on the crossability of 21 identified monosome lines (chromosomes 2, 4, 6 and 18) and one monotelodisome line (chromosome 11) with a donor line of Pima 3-79 G.barbadense L. As a result, it was found that the crossability of two monosome lines on chromosome 2 differed significantly (from 33.33 to 66.67%); 13 monosome lines on chromosome 4 differed from 12.50 to 100.00; 5 monosome lines on chromosome 6 also differed significantly (from 26.32 to 60.00%). The crossability of the monosomе line on chromosome 18 was characterized by a strong decrease (up to 16.66%), while the crossability of monotelodisome line (on chromosome 11) had the highest value (100%).
